The pourpose of this exhibit is: To review anorrectal anatomy. To review the types of perianal fistulas and their complications. To describe high resolution MRI techniques for anorrectal evaluation using phased-array coil. To describe high resolution MRI findings of perianal fistulas. To show the accuracy of new MRI techniques  for the identification and classification of anal and perianal fistulas and their complications. To show the usefulness of MRI to help surgical planning to minimize recurrence and detect clinically unapparent disease.  

High resolution MRI protocol of anorrectal anatomy. Anorrectal normal anatomy. Pathological MRI findings of perianal fistulas and their complications. New applications MRI techniques: Diffusion-weigthed Fusion T2-w- DWI-w images Scan dynamics T1-w gradient echo with fat suppression with color map graph and time-intensity curves.
